how much horse power does it have?

Asked by: Smitty2015
Thanks for your question. We tend to stay away from horsepower simply because organizations rule set differ, the method for horsepower testing in the field varies, and your final choice of exhaust systems will impact horsepower. Between all of these variables you can see a several horsepower difference. With that said to give you some general numbers, the World Formula will be approximately around 11.25 hp
